Title: The heavens declare the glory of God; and the firmament sheweth his handiwork.

1The heavens declare the glory of God and the firmament sheweth his handiwork. Psalm 191 2(No Transcript) 3If you look up at the sky at night, the heavens appear to be unchanging. In 1917 Einstein wrote down the theory of General Relativity. His equations indicated that the universe wasexpanding and decelerating. He believed that the universe was unchanging so he put in the cosmological constant to fix his equations. 4In 1929 Edwin Hubble found that galaxies are flying away from us in every direction. The farther they are, the faster they are receding. This is evidence for the expansion of the universe. 5The Big BangScientists now believe that the universe began in a tremendous release of energy known as the Big Bang. The universe has been expanding ever since. Evidence for this

Observation of galaxies flying away from us in all directions (Hubbles observations).

6(No Transcript) 7Expansion of the UniverseThe expansion of the universe can be viewed as stretching the spacetime fabric of the universe. It is He who stretches out the heavens like a curtain and spreads them out like a tent to dwell in. Isaiah 4022 O Lord my God, Thou art very great Stretching out heaven like a tent curtain. Psalm 1041-2Light waves get stretched out by expansion. 8Chance of winning the Publishers Clearing House Sweepstakes1 in 10,000,000 (roughly)Chance of getting the initial density of the Universe correct (at 10-40 seconds after the Big Bang)1 in 10000 0000About 55 zerosThe initial density of the universe must be very close to the critical densityInitial density_ 1 0.0000000001Critical densityAbout 55 zeros 9Origin of the UniverseScientists believe that the universe began in a tremendous release of energy known as the Big Bang.

Remnant of the Big Bang known as the Cosmic Microwave Background Radiation.

10In 1964 Penzias and Wilson discovered the remnant heat of the Big Bang. This is called the cosmic microwave background radiation. It is all around us. The universe has cooled off considerably. The radiation corresponds to a temperature of 3 degrees above absolute zero (- 454 F). 11Origin of the UniverseScientists believe that the universe began in a tremendous release of energy known as the Big Bang.

Observed abundance of light elements made in the Big Bang matches predictions.

12Star FormationEventually the universe cooled and atoms formed. With the help of gravity these atoms (mostly hydrogen) clumped together to form stars. 13ATOMSPROTONNEUTRONELECTRON()(0)(-)HYDROGEN ATOM (H)Combine 4 hydrogen atoms to make a helium atom. This is called fusion. It powers the sun.4HELIUM ATOM (He) 14NUCLEOSYNTHESIS Making heavier atoms by combining lighter atoms. This occurs in stars and is called fusion. This is where stars get the energy to shine.844

(Carbon dioxide, carbohydrates) The nuclear energy levels determine the rate of production of carbon and oxygen. These levels have been carefully tuned so that both carbon and oxygen are abundant.

If stars were 10 times closer (2 trillion miles), a nearby star could pull the earth into an eccentric orbit and kill life here. If the stars were much farther apart, then there would not be enough heavy elements to make life. Heavy elements (like carbon and oxygen) are the ashes of dead stars and living things need these elements. 17Protons and ElectronsPROTONELECTRON(-)()Protons are positively charged and electrons are negatively charged. A proton is attracted to an electron, but a proton repels another proton, and an electron repels another electron. This repulsion is 1039 times larger than gravity. Fortunately the number of protons equals the number of electrons in the universe. If this were not true, the repulsion between the excess protons (or excess electrons) would overwhelm gravity and there would be no stars, or planets, or galaxies. 18The Strong ForceThe strong force is the force that holds the protons and neutrons together in the nucleus of an atom. It is just sufficient to overcome the electrical repulsion between the protons.protonneutronHelium atom

If it was much stronger, big nuclei would form. There would be too many heavy elements like lead and iron, and not enough light elements like hydrogen and oxygen. So water would be rare.

If it was much weaker, it would be hard to fuse hydrogen. Stars wouldnt shine. Heavy elements would be rare.

19WaterWater vapor in our atmosphere blocks most of the harmful rays from the sun, e.g., ultraviolet radiation. Fortunately, however, it is transparent to visible light. Otherwise the sky would be dark all the time. 20Science and ChristianityToday science and Christianity are often viewed as opposing points of view. However, this was not always the case.

The scientific method of experimentation arose from the Christian world view that God is rational and unchanging.
